Carousel Coffee Roasters

I have inherited two "Carousel" coffee roasters, these roasters can do from 1lb to 15 lb per roast and take 2.5 minutes to rotate an eight bin horizontal carousel roaster. They work on electric generated heat. I cannot find any information on the internet regarding which company made these roasters nor was there any written documentation with them when I received them. Does anyone have any idea who makes them or who I can contact for more information?
